Ocean currents influence climate patterns by redistributing heat around the Earth. Warm ocean currents bring heat from the equator towards the poles, which can result in milder climates in regions that the currents flow through. In contrast, cold ocean currents bring cooler temperatures from higher latitudes towards the equator, affecting the climate of areas they pass through. Additionally, ocean currents also impact precipitation patterns and can influence weather phenomena like El Niño and La Niña. Overall, ocean currents play a significant role in regulating global climate patterns.
